在Kotlin中使用yahoo时发生了StringIndexOutOfBoundsExceptio错误

Question

我正试图通过在Kotlin使用雅虎财务api获取股票价格信息。https://financequotes-api.com/ --我编写了引用描述的代码，但是我一直把StringIndexOutOfBoundsException: String索引超出了范围：-1，出现了一个错误。等级和最优惠的设置附在下面。

package com.jym.assetallocation


class MainActivity : AppCompatActivity() {
    private val vBinding by lazy {ActivityMainBinding.inflate(layoutInflater)}


    override fun onCreate(savedInstanceState: Bundle?) {

        super.onCreate(savedInstanceState)
        setContentView(vBinding.root)
        vBinding.testBtn.setOnClickListener {

            Thread(Runnable {
                try{
                    val stock = YahooFinance.get("AAPL")
                    val price = stock.quote.price
                    Log.d("test", price.toString())
                }catch(err:Exception){
                    Log.d("test", err.toString())
                }
                this@MainActivity.runOnUiThread(java.lang.Runnable {
                })
            }).start()
        }
    }

}

dependencies {
    implementation group: 'com.yahoofinance-api', name: 'YahooFinanceAPI', version: '3.5.0'

由于我直接下载了文件的最新版本并使用它，所以它正常工作。
